Description

Portable ammeter

Technical Field

The utility model relates to an ampere meter technical field specifically is a portable ampere meter.

Background

The ammeter is made by the action of magnetic field force applied to the current conductor in the magnetic field. The ammeter is internally provided with a permanent magnet, a magnetic field is generated between poles, a coil is arranged in the magnetic field, two ends of the coil are respectively provided with a hairspring spring, the springs are respectively connected with a binding post of the ammeter, the springs and the coil are connected through a rotating shaft, and a pointer is arranged at the front end of the rotating shaft opposite to the ammeter. When current flows, the current passes through the magnetic field along the spring and the rotating shaft, and the current cuts the magnetic induction line, so that the coil deflects under the action of the magnetic field force to drive the rotating shaft and the pointer to deflect. Since the magnitude of the magnetic field force increases with increasing current, the magnitude of the current can be observed by the degree of deflection of the pointer.

The wire clamps used in the measurement are all composed of wires and conductive clamps, some wire clamps are connected with the ammeter, but the overlong wire clamps are exposed outside and are easy to damage. In addition, if an electrician goes out to work, the ammeter is placed in a tool bag or a tool box, and in case that the tool bag or the tool box is damaged or lost, the ammeter needs to be held by hands, and the hands cannot do other things, so that inconvenience is caused.
